'SULKY-PLOW.

BPECIPICATIONiorming part of Letters Patent No. 307,834, dated November 11, 1884.

Application filed August 4, 1884. (No model.)

To all whom, it may concern.-

Be it known that I, J OSEPH P. BLACK, a citithe county of Madison and State of Illinois, have invented a new and useful Improvement in Sulky-Plows, of which the following is a specification.

The nature of my invention relates to sulkyplows of that class provided with a truck, to which the front end of the plow-beam is connected, and a sulky in rear of the plow; and it consists in certain improvements, which will first be described in the specification, and atterward pointed out in the claims.

Referring to the drawings, like letters refer to like parts in all the figures, in which Fig ure 1 is a reduced perspective view of my improved sulky-plow, shown as standing on level ground. Fig. 2 is a plan or top view showing the position of the several wheels relative to the plow. Fig. 3 is a side elevation showing how the lever operates to elevate and depress the forward part of the plow-beam and plow. Figs. 4 and 5 are rear views of the truck, showing the construction of its axle provided withtheking-boltA,also showinghowthetruck is tilted or inclined when in and out of work. Fig. 6 is a rear View of my improved sulkyplow, showing position of the wheels and plow when at work. Fig. 7 is a perspective view, enlarged, of the king-bolt A, showing how its head a may be provided with a swivel-eye, a, made solid therewith. Fig. 8 is a side elevation of parts-the truck, plow-beam,walkingbeam, and operating-levershowing how the truck-axle may be tilted forward, the forward end of the tongue have movement up and down, the walking-beam R sliding in its connection with the plow. Fig. 9 is a perspective view, enlarged, of the swivel-eye made separate from the king-bolt for attachment direct to the axle.

Brepresents the truck, 0 the plow, and D the sulky or carriage, the truck in advance and the sulky in the rear of the plow, as shown.

The plow C may be the well-known plow, having a bent beam, 12, and provided with the usual mold-board and share, as shown.

The truck B consists of an axle, 0, having an arched center, two supporting-wheels, E and F, the tongue G, rigidly attached to the said axle, brace, or adjusting bar (I, to which the tongue is also attached, and the king-bolt A and swivel-eye a, rigidly attached to the said axle, as shown; and a supporting-bar, 6, may be connected to the said king-bolt and its ends attached to the said axle 0, providing support and steadiness to the said king-bolt, as shown.

The king-bolt A, I preferably construct with a main part or post, a, for connecting the plow, a fiat cross-bar head, a, for attachmentto the axle c, and the swivel-eye a may be made solid with the said head, as shown in Fig. 7. The swivel-eye a may be made separate from the said king-bolt, as shown in Fig. 9, and attached to the axle c with bolts or rivets, as shown in Figs. 4 and 5. The truck Bis connected to the plow Oby the perforated bracket f, rigidly attached to the beam 2), and loosely embracing the post a in such a manner as to admit the said bracket to slide up and down on the said post, and the post and truck to turn and tip or incline, as shown in the drawings. The frame of the said sulky D consists of an axle, 9, provided with the usual crank-arm, g, and lever g, and segment g', for adjusting the said crank-arm,and bars h and h,both of which have their rear ends rigidly attached to the said axle g and their front ends joined and attached to the plow-beam b, as shown. The seat a may be supported from the said axle g by the usual spring-bar i, as shown in the drawings. The foot rail or rest j may be attached to the said bars h and h, as shown, providing feet-rest for the operator. The said sulky-frame is provided with the usual wheels, H H, one rotary upon the arm of the said axle, the other upon the said crank-arm, as shown.

It represents a notched segment rigidly attached to the bar h, and Z the operating-lever pivoted on the said segment, and provided with the short arm at and the usual thumblatch, r, and lock 8, as will be understood by inspecting the drawings, Figs. 3 and 8.

R represents the walking-beam fulcrum, connected to the said plow-beam by the bracket a, which said bracket is rigidly attached to the said beam, and pivotal pin orboltn. The said walking-beam is provided with a central oblong slot, n, by which it is loosely pivotal on the said bolt n, and permits the said walkingbeam to slide and move forward and back on the said bolt to compensate for the tilting for ward and back ofthe truck. The front end of the saidwalki'ng-beam is loosely connected with the swivel-eye a, and the rear end provided with thelink o and connected to the short arm m of the lever Z, as shown.

In operation the operator moves the lever Z, tilting the walking-beam, gaging the depth of plowing, and elevating and letting down the plow out of and into work, as will be understood by the dotted lines shown in Fig. 3. The truck turns by the king-bolt being pivotal in the bracket f, turning corners and about, as will be understood by the dotted lines in Fig. 2. The tongue may move up and down, and the truck-axle incline forward and back, and the walking-beam slide forward and back, as will be understoodby the dotted lines in Fig. 8, showing the tongue dropped or lowered, the axle tilted forward, the walking-beam drawn forward, the slot a sliding on the pin or bolt n, by which the plow may pass across valleys and hills, while kept at a uniform depth of working by the lever Z, locked into the segment is.

I am aware that a truck in advance of the plow with a sulky in its rearis not new. Such I do not broadly claim.

Having thus set forth my invention, what I desire to secure by Letters Patent of the United States, is-

1. The truck consisting of an axle having an arched center, two supporting wheels, tongue, brace, or adjusting bar, king-bolt, and swivel-eye, in combination with the plow and the sulky or riding-carriage, substantially as and for the purpose set forth.

2. The supporting-bar e, king-bolt A, and axle c, in combination, the said supporting-bar connected to the post a and attached to the said axle, substantially as and for the purpose set forth.

3. The walking-beam R, fulcrumed connected to the plow-beam b, truck B, pl'ow O, and sulky D, the front end of the said walkingbeam having a loose connection with the said truck, and its rear end connected by a link, 0, with the short arm of the operating-lever Z, substantially as and for the purpose set forth.

4. The walking -beam R, provided with a central oblong slot, in combination with the truck B and plow C, substantially as and for the'purpose set forth.

5. The combination of the lever Z, provided with the short arm m and segment k, with the walking beam R, fulcrumed connected to the plow-beam 12, its front end loosely connected to a truck in advance of the plow by means of a swivel-eye, and its rear end provided with the link 0, connecting with the said short arm, substantially as and for the purpose set forth.

6. The combination of the plow O and sulky D, the former being in advance of the latter,

a truck in advance of the said plow, with the walking-beam R, link 0, segment k, and lever Z, the said walking-beam fulcrumed connected to the plow-beam, substantially as and for the purpose set forth.

7. The combination of the truck B, plow C, and sulky D, the said truck being provided with the king-bolt A, the said plow provided with the walking-beam R,with link 0, and the said sulky provided with the lever Z and segment k, substantially as and for the purpose set forth.
